The LM25180QNGURQ1 is an AEC-Q100 Grade 1 automotive primary-side regulated (PSR) isolated flyback DC-DC converter from Texas Instruments, packaged in 8-WSON tape-and-reel form, supporting 4.5V to 42V wide input voltage, integrating a 65V,1.5A power MOSFET, removing optocoupler or auxiliary winding requirement, achieving ±1.5% output regulation accuracy, operating at -40°C to +125°C ambient temperature, designed for compact isolated auxiliary power supplies inside automotive electronic systems.
Key Features and Applications
● Primary-side regulation architecture eliminates optocoupler and transformer auxiliary winding, reducing BOM cost and PCB space for isolated power designs.
● Integrated 65V,1.5A N-channel power MOSFET with 0.4Ω Rds(on), supporting boundary, discontinuous and frequency foldback operation modes for high efficiency.
● AEC-Q100 Grade 1 automotive qualification, low EMI performance compliant with CISPR25, with optional output thermal compensation to improve precision.
● Precision enable, programmable or fixed 6ms soft-start, hiccup over-current protection, input UVLO and thermal shutdown for robust fault protection.
This automotive PSR flyback regulator is widely used for isolated auxiliary power of automotive body control modules, EV/HEV gate drive bias supplies, automotive gateway power units, battery management system auxiliary rails, industrial isolated sensor power and 12V/24V vehicle bus isolated power conversion requiring simplified isolation design.
